Step-by-step explanation:
y = 4x-1
2x+y = 5
2x+(4x-1) = 5
6x - 1 = 5
6x = 6
x = 1
Answer:
<em>an= 3+12n </em>
Step-by-step explanation: <em>the sequence is 15,27,39,51 The first term is : a 1= 15 The common difference of this sequence : d= 27 - 15 </em>
<em>The nth term of an arithmetic sequence is given by formula an= a + (n - 1 ) d . so a n for the sequence will be : </em>
<em>an =15+ (n-1) 12 </em>
<em>an = (15)+12n - 12</em>
<em>an = 3 + 12n</em>

Step-by-step explanation:</h2>
The window is shown below, so we have two trapezoids. A trapezoid is a quadrilateral (polygon with exactly 4 sides) where at least one pair of opposite sides are parallel. The area of a trapezoid can be found as:
Since there are two trapezoids and each with identical dimensions, we can find the area of the window by finding the area of one trapezoid and multiplying this result by 2:
Finally:
Order from least to greatest
-9/2, - 3, 1/2, sqrt(6), 4.2
answer
D.-9/2, - 3, 1/2, sqrt(6), 4.2
----------------------------------
sqrt(10) is irrational number and real numbers
answer is B.irrational number and real numbers
-------------------------
square root (81) = 9
square root (100) = 10
square root (93) is between 9 and 10
so answer
9< sqrt(93) < 10
